Additional Product Features and Benefits:
WQB3000 BGA/QFP Rework Station
• The unit features a two head system for component placement and hot air
• The two heads operate on sliding arms, which are controlled by pneumatic
• The control electronics and pneumatic unit are intigrated into the rear
• LED’s on the back of the housing panel indicate four process states: top
• RS-232 interface for data input unit or PC control. An easy-to-use PC
• The connection for the hot air nozzle temperature sensor is in the soldering
• Precision linear feed for vertical adjustment, approximately 3.2" (80 mm)
• A continuously adjustable depth stop prevents the head from dropping onto
• The head mechanisms are pneumatically damped to give you finer control
• A vacuum lift built into the hot air nozzle allows for the automatic desoldering
• Theta rotation of the soldering head in a range of -5° to 95°
• A swiveling halogen light is mounted near the soldering and placement heads
• A wide range of easily interchangeable hot air nozzles are available and are
Applications:
• Rework and repair of SMT array packages including ceramic, and plastic, BGA’s, micro BGA’s, Chip Scale Packages, PLCC’s, and QFP’s. Multi-layer boards and
